💕Happy late valentines/ace week!!! 💕

This piece is a celebration of animals that can reproduce asexually in various ways. Under the readmore you can find a key to the species included and some information about how they reproduce.

These are very simplified definitions, if you're interested in this stuff definitely do more research and reading! The intricate details are really fascinating and specific to each animal- plants are even crazier!

Budding: a new individual develops then detaches from the parent when mature

Fragmentation: a new individual grows from a detached piece of the parent organism

Parthenogenesis: a new individual forms from an unfertilized egg

Facultative Parthenogenesis: the organism can reproduce sexually and/or asexually

Obligate Parthenogenesis: the organism can only reproduce through parthenogenesis

Gynogenesis: a form of obligate parthenogenesis that requires the presence of sperm without any actual genetic contribution

Planarian is able to regenerate any missing organ, which has made planarians a popular model in research of regeneration and stem cell biology.
